[gccb]

hi got a 2.5 tdi touareg from 2005 with very bad acceleration,at P or neutral position car accelerates very bad and when i put it on D acceleration won't respond, the strange thing that i got nothing on scanner, car starts ok .
any one can help please?

Start with basics- how's the fuel filter and air filter? MAF readings? Turbo operating? EGR condition? Blocked inlet manifold?
Vacuum pipes all fine?
Does it have a DPF? Is it blocked?

Didn’t know you worked for the Spanish Inqusion DeigoStud

What color is exhaust smoke?

can you start engine and jam the air intake with DK Thanks see if it still runs
split interccoler? If it is, dk thanks mixer with glue great for that

already checked maf,egr,inlet manifold and turbo , all seems to be good, car don't have dpf

Either they or good or their not not seem good

i would report back with full answer of deigostud, if you dont he will tighrn thunb screws.

have you gas axed the exhaust off?

bad camshaft/cranckshaft synchronisation could be a reason?? i don't have related fault on scanner just a supposition.
also i have coolant temperature sensor and brake switch malfunction read with launch but in live data i have pedal not pressed.
i saw lot people on other forums getting such problem but they didn't report back with solution.
is here someone already dealing with such problem???

1) your lunch could. Be wrong indian code
2) is the ecu sat in water?
3) if ecu not sat in water is there a nearby river?

problem solved, it was a bad cam/cranck shaft timing,checked it again and now car running good.
on those models scanners may not help , you have to put all your knowldge on desk.
thanks for ur help
