have a 110 with a 200tdi retro fitted by the stealers that has about 150,000 miles on it.
Recently went up to Billing and the engine was pulling fine. I need to fill up about 20 miles from the Billing.
On leaving on Sunday the engine was down on power. I pulled into the services and the engine was surging when idling. I have drained the fuel filter thinking there was water in it, but this has not resolved the problem. The diesel that came out was very clear and did not have the characteristic reek of diesel.
Does anybody know where to start looking to resolve the problem
