Hi I am new to forums and not a technical when it comes to cars.
Please note the problem only occur when it has been raining.
I have a VW Golf 1.9TDI 2006 70,000 miles - well serviced, round trip of 48 miles to work on motorway and country lanes.
Several months ago it would lose power - limp mode BUT only when there had been heavy rain.
On one occasion this occurred at 65mph on the motorway - a great deal of road spray.
The power loss occurs at 30mph in 4th - drop to 3rd and rev up only to find loss of power.
The car has been into a VW dealer.
Salient points - the engine management light has never come on (except when first turning ignition key)
the diagnostic at the dealer shows no error codes. The dealer contacted VW Uk - the Ecu was cleaned up etc. Car satisfactory for a while bur problem re-occurred - result a new ECU (not cheap these things)
Again car ok for a while. Last week problem came back - recovery vehicle brought me home.
Took car out today - torrential rain - pulled into a car park and left engine running to warm it up. Slightly depressed the accelerator - up to 1500 revs - revs dropped back to idle. this occurred several times plus several times the revs did not increase at all even with depressing the pedal about half way. I am talking to the dealer tomorrow - but I know they are puzzled also - can anyone offer suggestions please - many thanks
