I have been having some major issues recently with my -
Audi A4 b7 S-Line 2.0 TDi
8ec 140hp BRE 2005 158k
It is currently dead and wont start at all, just strange strangled gargling skooshing sounds when i turn the key on full. The half turn comes on fine with the engine and battery lights on and my diagnostics say no error or fault codes at all. There was a serious engine shake on idle and really eratic acceleration control in low gears. Lots of toxic fumes in through the vents so had to use recirculated air. AC dryer cylinder pipe waa snapped off and ac oil cooler badly dented on bottom left from previous owners undisclosed front ender. The clutch felt crunchy and rattly too like the bearing was corroded and there were lots of noises from around the timing belt tensioners / altenator area like loud ticking / spitting. The n/s intercooler has a small hole / dent in it and appears to have hemorrhaged oil pretty heavily with staining about 2 inches from the bottom edge upwards. The turbo was starting to feel like it was maybe heavily choked up, egr and possibly breather tubes and exhaust system too. Engine bay was getting stupidly hot but oil temp read fine on the gauge. Felt a lot of power loss and as if it was really struggling to breathe, then started feeling really seriously rough in all gears and distinct lack of power. Used fuel additive to try help in case the tank was full of crud which it must be and had thought maybe injectors needed cleaned. It seemed to work well on a full tank but soon as i hit the half tank of diesel it got mega rough and worsened to nearly quarter tank then it just refused to start again.
I have these bits of advice so far:
EGR remove and clean
Fuel filter replace
Fuel pump replace
Fuel pressure release valve replace
Start with aerosol in the intake
Carbon cleaning service
Dryer cylinder and pipes for ac
Ac oil cooler panel
Timing belt, tensioners replace
Water pump replace
Altenator pulley and tensioner replace
Clutch bearing
If this list sounds right I will report back as I go and see what works. Any other help and advice will be greatly appreciated. Im no expert just been reading up on anything that sounds like similar issues / symptoms.
