Hi to all, I'm a newbie to the forums & to Audi's, I had hoped one of my first posts on here would be a more positive one after picking up my 2.0 TDI S-line sportback 4 weeks ago.
I'd been looking for a TDI sportback for weeks & one came up at reasonable money with FASH so it was snapped up. Having driven an older tuned AMF TDI PD car for the previous 8 years I was amazed at how silent & smoothly it ran (the loudest noise was the turbo whistle), & was absolutely delighted with it. After a couple of weeks the previous owner contacted me to say they had received a letter from Audi regarding the injector recall & that he thought I should conatct Audi to get it all checked out, which I did. The car was booked in & I was told that all 4 injectors + the loom would be replaced.
When I dropped the car off I had had no issues with it at all, it ran perfectly. However since picking it up, whilst it may drive ok it sounds like a bag of spanners - very agricultural. I'm now having to take the car back to Audi for further inspection but am trying to arm myself with as much info as possible & was wondering if anyone else has experienced this problem?
Below is a quick list I put together of the issues:
Car running perfectly 16/04/12, 8.30am, taken to Audi Epsom (Drift Bridge) for recall on potential Siemens injector & wiring loom fault.
Injector units x 4
Injector loom? – Not listed on service invoice
Injector seals? – Not listed on service invoice
Since collecting the car 16/04/12 15.30pm car has not been running correctly & sounds like a tractor.
Rough idle compared to before – Much more engine movement, very reminiscent of an old 3 cylinder PD TDI I used to own.
Excessive ‘diesel knock’ – Engine was practically silent before.
Extremely loud on idle compared to previously (excessive top end rattle).
Engine ‘pulsing’ on idle can be heard from exhaust as if engine revs going up & down although nothing is showing on rev counter. Sounds like one of the cylinders is not combusting correctly
Major noise/vibration at 1200-1500 rpm (shakes the car).
Engine is now sounding very ‘agricultural’ with the top end rattling throughout the rev range regardless of whether the engine is hot or cold.
Hot & Cold starting not as instant as before – could almost ‘flick’ the ignition & the engine would start, now needs to be turned over.
Injector cam rockers not adjusted properly.
Injector cam rocker assembly not fully tightened.
Injector timing not adjusted correctly in VCDS/VAG-COM.
Injector seals not fitted correctly.
Injector units not seated correctly.
Thanks in advance for your help
