Car Forum / Mercedes-Benz Cars / May 2007Petrol smell in cabin in 190E
1993 190E auto. At times I notice a petrol smell in the cabin after the car has stood overnight or longer. There is no obvious leak and no service person has ever commented. Your suggestions welcome. Many thanks. DAS For direct replies replace nospam with schmetterling --- Are you sure it is gas not oil? Oil is possible in the car as the oil pressure gauge does use oil line on some models... like the 2.3L. If you are positive it is fuel, then I'd say it is probably the warm up regulator on the side of the fuel distributor... black retangular thing... again, this is on 2.3. Thanks, but I have the 2.0. I am pretty sure the smell is not oil. DAS For direct replies replace nospam with schmetterling --- > Are you sure it is gas not oil?

I think it is located atop the tank under the rear window shelf.  SignatureRoland Franzius Thanks, chaps, I'll look at both.

Dori, almost certainly it's the little black plastic cuboid on the side of the air intake ,,, same happend on my 300E. This is the EHCU or some such similar alphabet soup. In short it controls the fuel distribution pressure to the injectors. This $300 CDN gizzmo leaks after time and can't be fixed. The leak is tiny at first but gets worse and more noticable. cheers, guenter >1993 190E auto. At times I notice a petrol smell in the cabin after the car >has stood overnight or longer.
