Slight misfire/hesitation ???

[ihs61]

Hi

This question is for one of my computer illerate buddies.

He has a 55 plate A4 B7 2.0 Tdi 140 S-Line with 117,000 mile FSH.

It has an occasional very slight hesitation/misfire/judder, it has done this for the past couple of years but is becoming more frequent.

It happens when coasting along in traffic with a steady throttle pressure, ie just on. Engine revs 1800 - 2400, the moment he puts his foot down the cars away with no hesistation.

He's been told to ignor it until he gets a warnimg light as it will be easy to find the fault with vagcom.

He has tried a can of erg cleaner, load of crap from the exhaust but no improvemnt.

Any suggestions kindly welcom.

Has he had the injector recall done?

He has had the car for 3 years, in that time its not had any injector work done nor is their any mention in the service history.

its a 140 not a 170 so no recall

Quite right, missed that

We have had a few with split boost hoses and boost leaks. I spend a lot of time using my VAG pressure testing kit these days and I find a lot of boost leaks.
