Hi everyone,
I'm new to this forum, just signed up to ask for a bit of help with my Passat, which has recently developed a running issue. My sincere apologies if this problem has already been clearly diagnosed elsewhere, I'm not very forum savvy.
I have an old 2001 B5.5 Passat TDI that was running like an absolute gem. A week or two ago, I noticed that on any given day, when I first got onto the motorway and put my foot down, I would get a few little coughs, reminiscent of fuel starvation on an old carb engine. These coughs would cease if I eased off the pedal, and after a few minutes of taking it easy, I can put the foot down again, and it is fine for the rest of the day.
Then, this week, as I was driving around the oxford ringroad, it did it much worse, to the extent it felt like I was driving on three cylinders (eg: if an old petrol car did this, I would have checked the HT leads), with lots of vibration, and obvious miss, and lump idle.
The next day it was fine again, but since then it has come back a few times while driving, usually starting with a few coughs. At slow speeds it feels like running on 3. At fast, it feels like I'm driving on very aggressive rumble markings.
I've also now discovered that stopping, turning the car off, waiting a few minutes, then starting again temporarily solves the problem.
I'm waiting on a friend to come round with a scanner in a few days. In the meantime, does anyone recognise my issues?
Many thanks for taking the time,
Matt
