I have a 2007 B6 Passat 2.0TDI with ~67k on the clock which has developed what can only be described as a momentary stutter/hesitation at about 1800-2000rpm and is difficult to hold it at that speed due to the hesitation. Sometimes it’s worse/better but I can’t pin down any consistency. It clears as soon as you speed up and the car seems fine otherwise but it’s obviously a niggle. Fuel economy does seem to vary quite a bit and I’m wondering if that’s linked somehow.
It’s well serviced, both by me and the previous 1 owner. So well serviced in fact I’ve had to get a new service record! No fault codes are logged (as far as I can tell – I have a cheap OBD scanner + app)
It gets pretty regular motorway runs, but is mostly used for commuting and running about locally. It’s had a fuel system cleaner (Forte) put through it more than once, injectors were replaced in a recall at about 30k miles. No DPF on this car.
Any thoughts STW before I take it to a local diesel specialist?
