I have scoured the forum for suggestions but haven't found a lot for W202 specifics, so am hoping people might have some advice.
I picked the car up, fairly cheap, a few weeks ago. I could tell it wasn't perfect but the money was right, it had good history and only 120,000 miles, so I went for it.
So far:
-have changed the thermostat- now sits a 80/85 degrees rather than 50-60.
-Re-seated injector number 4, which was leaking- Black Death had already begun.
- run some Wyn's formula gold through a tank of diesel.
-changed a very grubby looking fuel filter and put in a new air filter.
Car is running a lot better already. Starts perfectly. However, still has the following symptoms, some of which might just be characteristics of the car, so am fully prepared to be told that.
- tapping/ticking noise from top end somewhere- particularly noticeable when cold, does virtually disappear when fully warmed-up.
-sluggish in first gear, at least until 2000 rpm. Worse when cold, although not great when warm. As soon as it reaches 2000, it flies along and happily revs up to 4500 rpm if you keep your foot down.
- along with the sluggishness is a air bit of black smoke, not horrific, but looks like a lot in the headlights of the car behind you. Smoke remains high while accelerating hard. Although steady acceleration with changes at 2000/ 2500 rpm doesn't really produce much, as there is very little smoke at tick over, after the initial brief puff.
- turbo fairly noisy- aware of it spooling up to speed and spinning down. Are they fairly noisy anyway? Also drive a jtd Alfa so that's all I can compare to- it is a lot younger and fresher in fairness.
Am reasonably competent and engine seems very workable (again compared to Alfa) so wondered if anybody could give me a idea of where to start, in terms of an order of components to clean/check/get tested.
My initial thought is to get injectors tested, although also know that could see me spending four figures. And/or EGR valve- dismantle and clean. Checking pipe work between turbo / intercooler / EGR for leaks as could explain turbo noises?
Any corrections or additions would be gratefully received. My local Indy has a reasonable reputation but is expensive in my opinion. And I'd rather work through sorting it out myself if possible, even if I takes me a few weeks.
Thanks very much.
