The SI lights on my E30 are telling me it's time for an Inspection 1
service, but I'm struggling to find an online resource detailing
exactly what work I should carry out at this point. I did the discs and
pads last year, and the oil & fluids are about 9k miles old. I'm
planning on doing the belt and tappet adjustments some time this
summer. Does anyone know where I can find a list of other items that
should be checked or replaced at Inspection 1? The car's a UK 1990 320i
with about 140k miles.
Initially the service indicators were a complicated function of engine
load / mileage / age etc. BMW then realised that the interval was
actually directly related to the amount of fuel burned and they now base
the interval on that. To further simplify things I have always found the
interval to be fairly static at about 6,500 to 7,000 miles no matter how
I drive. Simply put; change the oil religiously with a filter every
interval - it is cheap preventative medicine, and change the timing belt
every 40,000 miles; everything else can be looked at as and when it
needs doing. Brakes by inspection ( although new fluid every couple of
years is a good idea ) valve clearances - have a look and see - fiddly
but relatively simple job. The real secret to servicing cars is NOT to
just leave it to when the manufacturer says things need doing but to
understand your car and keep an eye on stuff - especially fluid levels.
I'll stop waffling now.
P.s. if you go to BMW they will actually provide you with a service
schedule - in fact I think that it may be in your manual.
Thanks, I was aware of that, it was more a case of wanting to know, for
example, whether they recommend the gearbox oil being changed at
inspection 1, or only at 2. The belt's due anyway, and it is obvious to
the ear that the tappets need adjusting so I'll do them at the same
time. I'm also half tempted to keep an eye out for a good M20B25 and
box, rebuild it and drop that in, but that's another story!
