    any DTCs are there technicians simply not trained to examine actual data or simply not trusted or worst allowed to think outside the box Perhapsit s just me But I couldn t exist in an environment where technical pride respect and ambition are suppressed The dealerships offer some excellent training programmes not withstanding their access to the relevant technical repair information So where and why does it so often go wrong I promised the guys on a weekend training course last week to conclude the tests we carried out with a repair solution For the benefit of everyone else let s start at the beginning The polo 1 4 GTI DSG employs a recent variant of the direct petrol injection system MED17 9 Initial first look confirms no DTCs however the vehicle did suffer extended cranking prior to starting Once started it ran smoothly Some 10 years ago I developed a process of testing hydraulic high pressure pumps using analysis from the pressure sensor profile Initially for common rail and later adapted to petrol high pressure systems Having no test data on this system variant it presented a perfect challenge to the diagnostic process Direct petrol injection is very similar to common rail diesel control and the initial test sequence began by looking at the key critical requirements 1 ignition driver s 2 injector driver s 3 rail pressure The result of this composite observation and we can now reveal our involvement in developing the new rainbow pico scope confirmed an unusually slow pressure build up Normally pressure build I refer to this as rise time should take no longer than 600 milli seconds and as little as 300 milli seconds our vehicle took up to 3 whole seconds The next stage in the process involves intrusive tests This Part of our past development programme was designing a low pressure test gauge the requirement was to monitor suction or positive pressure priming systems together with flow and the ability to conduct pump proof testing under real load conditions Applying this test confirmed excellent low pressure priming with 6 bar available to maintain high pressure pump pressure The most interesting aspect of our initial observations and unique so far for petrol systems Was that until a certain pressure was reached no triggering of fuel or spark took place We also noted that no driver outputs were present at the high pressure control valve therefor no current was present either This further confirmed our training group s findings that the valve is actually a volume control device Proving this theory also follows our common rail pump proof process removing current at 2k rpm immediately caused the pump to run at full pressure 115 bar The other intriguing part of the waveform profile was the accelerated decay time not normal for this pump type So the decision You need a new pump mate with just one cravat check the camshaft drive lobes and follower Othernon relevant issues found included a reduced burn time

    each component It s easy on a job like this and not know where to begin and I sometimes have to stop myself from diving in which inevitably leads to mistakes Firstly I acquired myself a diagram which labelled the precise order in which the turbo control system was plumed together There is a labyrinth of vacuum control hoses which not only deteriate over time but decide to move location flitting between components all by themselves Here is another diagram I stole from the internet Naturally I went through each and every single connection one by one to ensure correct fitment and to my surprise they were all absolutely spot on However the inlet bypass control pipe had been fit incorrectly and run through 90 degrees before it fitted onto the control solenoid making it crimped and restricting control vacuum I quickly re fitted the control hose and tested control functionality to all corresponding valves and wastegate I was abale to do this using the Autologic handset but don t worry if you haven t got access you can simply use your vacuum guage and mitivac to test each component The Autologic enabled me to select each component individually and drive it in sequence it even gave me the precise movement ratio to be expected from each actuator Exhaust bypass valve A 25mm Inlet valve B 15mm Turbo wastgegate valve 5mm When I initially tested the wastegate valve with a mitivac I yelped Eureka thinking I d found the problem as I witnessed the wastegate only slightly opening nowhere near that of a petrol turbo wastagate that we re all used to The correct opening travel is only 5mm If you re sneaky and whilst using a torch you can just see the actuator arm right down the back of the exhaust manifold altalternatelyu can remove the under tray for a proper look I ve stuck my screw driver to point out where you can see the arm With the engine running you can very easily see the main exhaust valve opening and closing in front of your eyes but as for the smaller and hidden inlet valve towards the fron you have to listen and detect a change in engine note whilst operating Using the vacuum guage I checked healthy vacuum operation at each component to ensure good control which varied between 0 20 inhg Confident I had checked every single turbo control valve and rectified the small issue with the vacuum control hose controlling the inlet valve a carried out a wide open throttle test and measured calculated air flow The engine responded much cleaner but soon deteriated and produced an unhealthy cough of black blue smoke and idle speed quickly deteriorated with the engine giving off a noticeable aquistic deep sound Keeping things simple I checked the target calculated Air flow against actual air flow and very quickly it was clear there was a problem Using the mitivac I was abale to manipulate the EGR position to allow the correct reading and desired engine note The valve itself was free and able to move willingly but for some unknown reason the ECU wasn t controlling EGR as normal It was at this point I simply decided to completely bypass the EGR through ECU calibration and software adjustment also making the necessary adjustments to boost control and DPF regeneration program for track use only After EGR was removed the car ran brilliantly and smoothly You might all be wondering why I didn t go straight for EGR in the first place as it s so easy to test but it s so tempting to get side tracked and lose focus of your repair I m glad I spent all the time to carefully check the Turbo control system a because I was getting paid to and b I learned a great deal about these systems and I hope I ve helped you with this topic Thank you for reading J My next article is bonkers and you re going to be convinced I m bonkers for even taking it on To wet your appetite it involves a none starting 204 chassis Mercedes c class which let s just say has been used to launch full amphibious assault on Normandy The next technical Era September 10 2014 0 Comments in Workshop Blog by Dave Massey By Frank Massey I was tempted to call this feature new technology it is however not all that new What s remarkable is the way in which the chosen technologies are fully integrated even in vehicles of a more modest price range The systems I have chosen are from the Audi range In writing this feature the real challenge was what to exclude as the chosen subjects represent just a small part of a fully integrated vehicle chassis and power train network Audi valve lift system cylinder on demand active noise cancellation active engine mounting Let s begin with the question why reduced emissions flexible performance passenger comfort market product advantage improved safety desirability In qualifying the above list I have just placed an order for the new seat Cupra 280 DSG which embodies many of the technologies discussed Variable valve lift and cylinder on demand employs the same technology The camshaft core is splined over which the camshaft lobes are carried on a sleeve The sleeve has a helical groove at each end The grooves control the lateral movement At each end of the sleeve is a solenoid which engages a pin into the helical groove thus causing it to move sideways when demanded by the PCM The performance variant moves a high lift lobe into engagement within a single cycle The cylinder on demand variant engages a zero lift base CAM thus disengaging the cylinder fuelling and ignition is also disrupted This later system enables the v8 engine to smoothly convert into a 4 cly The performance variant modifies both lift and timing employing firing sequence separation which improves exhaust flow increasing

    by core bearing failure Of course I cant prove my theory behind the motivation for long life servicing but I think I m onto something Please feel free to discuss and help me educate the motorists about the truth and value behind regular servicing I spend a huge amount of time and effort in order to educate and attempt to help my customers save money in the long run sadly it s often I ve after a major repair and replaced the turbo For training details and further info click www ads global co uk By David Massey ADS Half truth is lie February 19 2014 21 Comments in Workshop Blog by Dave Massey initial miss fire DTC s In the workshop recently we were presented with a BMW 1 series 116 petrol E87 model with a complaint of a hesitation under load or what can be described as a miss fire As always I initially interrogated the DME module engine ECU for DTC s I was presented with multiple DTC S SEE FIG 1 and so initially I decided to carry out a basic visual examination of the ignition coils and spark plugs The plugs did show early signs of spark erosion or corona ringing and the coils did look a little tired On the strength of my visual examination I advised the customer to replace the coils with brand new genuine coils and NGK plugs with the proviso that we would need to carry out extended tests after fitting the coils I took the time also to clean the throttle body and realign using Autologic and simultaneously reset and fuel trim adaptation values Once reassembled I took the vehicle for a quick test drive approximately 6 miles which delivered an acceptable level of performance and didn t present any dtc s So I took the decision to finish the bill which included 1 hour diagnostic time at 85 vat 1 hour mechanical labour 65 vat and 4 new Coils 25 x 4 and 4 new NGK plugs at approx 6 each Total bill 268 vat I m not afraid to admit I held a little reservation in my mind to wether we had correctly identified and fixed the problem so I warned the customer about the lack of hard evidence and the chance that there might be intermittent faults still present which haven t occurred during our test procedure but reassured him that what we have done for the cost is good common sense and the right place to start After a brief explanation of my findings and showing the customer the suspected faulty ignition components visually he paid the bill shook my hand and left It wasn t until 2 days later he came back with what can only be described as a disappointed look on his face when he turned to me and said its exactly the same Not surprised by this I said ok let s take another look offering the first hour diagnostic free

    low looked healthy on the low priority network The next test was to check power to the engine transmission ABS module and after removing the relevant plastic trim and chopping my way through the jungle all power supplies proved ok Still no comms to any of the above modules Based on the evidence it used to be a taxi and the possible disturbance to wiring in and around the dash assembly I decided to quickly drop the trim directly underneath the steering column Bingo The fuse panel on the driver s side A pillar had a multi plug CAN connector which had been violently hacked into and left disconnected I hate to say it but I told you so I soldered and heat shrunk the wiring back together and I was able no to communicate with all the modules After a quick crank The car sprung into life and stayed running I spent the next 4 hours gloating like Sherlock after defeating morriati and decided to completely reassemble the vehicle Since we had removed the cowling under the windscreen I decided to remove the rubber bung drain plugs and steam clean all the plantation from in and around the bonnet area I took the time top carefully dry and lubricate all the electrical sockets and replace all the missing hoses and trim I went through all the remaining dtc s and replaced several blown fuses I applied a BG 109 engine flush and replaced the engine oil and all the filters It actually started to look like a presentable and respectable car again I even took the time to remove the glue left on by the taxi company logo on the side of the doors Despite the cracked windscreen it looked mint Quality Costs less then you think March 25 2014 0 Comments in News Articles Workshop Blog by Dave Massey This article was kindly written by my good friend and colleague Sean Lynch of D S services based in London www facebook com Dsservs Quality Costs less then you think I was recently asked by a local engineering shop to look at an 07 Mercedes Sprinter that had drivability issues with a noise on the turbo but with limited boost On the initial diagnostic scan it pointed towards a turbo boost problem Before I condemned the turbo I performed a few procedures to test the related systems inter cooler and boost system exhaust egr and turbo control After these tests proved ok I was happy to conclude my diagnostics with a failed turbo Job done findings explained customer happy invoice paid End of story No A few days later came a phone call explaining that after the turbo was repaired if was refitted and there was no change in performance in fact it was slightly worse The original turbo had signs of oil starvation which tallies up with the lack of performance noise so what was done by this so called turbo specialist It all seemed ok on the
