525D - Cold Start Judder

Post by veeshy » 12 Feb 2013, 21:48

Guys

Iv read so much about the lumpy/judder on a cold start on the forum but there doesn't appear to be an direct solution. Iv found an array of solutions but i'm keen to know in what order would you have each of them looked into?

The last thing I want is to go and fix something only to find its not the fix, so i have listed a few things that could be causing the lumpy judder and wanted to know which would you attack first?

- Injectors
- Glow Plugs
- Air Filter
- Main Thermostat

Last time I had the car checked for fault codes it didn't bring back anything however i do know some diagnostic tools dont always give out all faults

Any views would be good.

Conventional wisdom will usually be easiest/cheapest first, so (approximately!)

Is the car manual? Could be a clutch issue.....

None of the items you mentioned would realistically cause a juddering.

It's a big lump up front, have you checked the engine mounts? You would probably notice if these were going even when the engine is warm as you'll fell it through the pedals, but worth a look as it's a cheap and easy fix and easy to check.

Don't discount your gearbox or exhaust either, I had a rumbling/judder only when cold on my car and it ended up being the exhaust banging around on something but during my search for solutions I found that a gearbox low on oil (ATF) can cause a juddering. When these things warm up the noise will disappear.
