Hi,

I went to test drive an Astra-J 2.0 CDTI 2011 last week and when I drove it, it was splendid, however when I got to 70mph under my seat I could feel what can only be described as an oscillating rumble, not loads, but like something was grinding. Only happened and 70mph, when I slowed down, it went away, and when I went over 70mph it went away, literally between 68-72mph.

Any ideas what that could have been?

Car is still available, if its something minor, I could go back to it.

I have a 63 plate astra 1.7 cdti a17DTC

This car came to me as a non runner,

was told it ran ok but kept going into limp mode due to SCV, previous keeper attempted to replace injector after leak off snapped and started leaking.
they unscrewed the top of the injector?

anyway since i have replace the injector, SCV and fuel pressure sensor on the end of the rail. still wont start

Hey guys

I have a 1.7 62 plate GTC. I have noticed there is a semi decent oil leak coming from the underside of the pipe , where my intercooler pipe meets my throttle body. The issue is, that the clamp seems to be in fully seated and there is no o ring so why is it leaking? I doubt it's a split hose as it was replaced a a couple years back for a new one at the garage where I bought the car?

Any ideas?

Thanks in advance [IMG]https://uploads.tapatalk-cdn.com/20210609/7eacd31e427b601533617216

Hey guys,

Noticed something alittle odd on my 1.7 Astra GTC 62 plate.

I was letting the car idle stationary and was hold the revs at certain ranged.to get the engine warmed up.

I noticed when the rev counter hit approx 1500rpm - 2000rpm I could feelnthe car shaking abit, but then below or above the rev range it would smooth out and be completely normal?

Any ideas on what it could be?

Thanks in advance.
