Help guys!
I own a 190d Turbo, 1987 model year, problem is intermittent turbo boost! I'll be driving along on the highway, all of a sudden, turbo stops... very suddenly! Drive a few more minutes and eventually it comes back! It seems to happen especially after a heavy rain, I have know idea what to look for... electrical??? I do all my own work, all factory parts, mb coolant and Shell Rotella synthetic 5W40 every 4500 miles, car has about 220,000 miles.

 

Clogged air filter? I'm not sure about the turbo model

 

You might want to check if you have a trap oxidizer (left side of engine, looks like an aluminum football), also call a certified benz shop, give them your VIN # and see if youre eligible for a factory recall.

My trap recall fixed about half my power issue on the freeways. Then I plugged off the EGR hose and it's almost back to normal.

good luck and enjoy
