Car Forum / Mercedes-Benz Cars / May 2005Puff of steam from grill - E220 Cdi 1999(V)
Every now and then I see some steam (not a lot) come from the grill when stationary. Although it happens after driving for a while, the temperature gauge has always been okay, (around about the half way mark). Any ideas? Thanking you in advance > Every now and then I see some steam (not a lot) come from the grill when > stationary.

If you stand outside the car you might hear a drop/sizzle Check the fuel pipes near the high pressure pump for leaks. It sounds silly, but I've seen alot of "steaming" grills that turned out to be a small, low pressure diesel leak. >> Every now and then I see some steam (not a lot) come from the grill when >> stationary.

This tricked me for awhile and after experimenting with a hose I found that this was the cause. Also my passengers would often become concerned which was the most frustrating. Check for leaks etc first as previously suggested,I would also check if the rubber seal along the bonnet/hood front and rear are intact. Just had a call from the garage. . .It was a small diesel leak - £250+VAT ! Thanks everyone for your help. |
