Has the car been standing for a long time? Does it run? Sludge in the coolant reservoir is sometimes a sign of head gasket failure - oil getting into the coolant. Does the car have a service record and has it had the head gasket changed in recent times? As a first pass, you could try draining the co...

I looked up the original parts list and got the following: 214 and 414 models GCV1060 RH GCV1059 LH 216 and 416 models (manual) GCV1062 RH GCV1061 LH and GCV1064 RH GCV1063 LH Not sure why there are two options, maybe revision on VIN number For automatic s it gives a number FDU2883 for Auto. Googlin...

Agree, it's less useful than it was. A while back, maybe quite a while back, they listed all the parts on the diagram with original part numbers including bits that are NLA. I guess you can still get that by clicking on one of the parts and see the diagram, but they don't now show NLA stuff. It's a ...

Most likely a fault in the driver door control box (or the lock button position). You can't lock yourself out of the car manually as the drivers door cancels the lock button unless you deliberately hold up the door handle. The central locking on our 1990 214 GSi stopped working after a few years and...

Thanks for pointing us to the YouTube video. https://www.youtube.com/watch?v=Az2u3-GLl1o I didn't know any of this or seen this test. I use Momentum as it's the nearest, though occasionally V-Power also quite close. I'd heard that Esso Supreme was low in ethanol but seems to be less good overall. I'...

The K-series should run on either, however I use the more expensive E5 (Tesco Momentum, Esso Synergy, V-Power etc.). The lower ethanol is probably better for the tank and various hoses and seals, and it's likely to absorb less moisture if left for a while. The other factor is that the ethanol adds o...

I expect the Honda engine alternator is an industry-standard type used on several different cars from that era, so spares for it are probably available to fix common faults such as the brushes/regulator or rectifier assembly. Have you been able to find equivalent part numbers from suppliers like Bos...

Interesting. The one on my early 214 is metal. Maybe more durable.

Have you tried adjusting the position? You can adjust the catch itself (three bolts holding it to the boot). I've found over time it can get pushed backwards and swivelled slightly sideways making it hard to lock. The fixed loop at the bottom can also be adjusted, it's held on by two Torx bolts. My ...

One other thought. Reading your initial message, you mentioned three intermittent faults. Did these happen simultaneously or were they individual at random times? If they happened simultaneously, then you are looking for some common circuitry.
