You are forgiven. G Reg is 1989/90, so it’s the first production year of the 4.0 models.
They even carried over the 2.9 engine until the 91MY cars arrived.

Hopefully getting the car back tomorrow after it’s had a replacement pump motor fitted. Fingers crossed this will resolve the braking issues and then I can concentrate on the boot leak.
I’m going to speak to a local paintshop about getting any work required done when the screen is removed. It would be nice to think that it would be a simple job to resolve but, I have this sneaky feeling........

Catch up time, it’s been eventful and, confusing!
The cars spent several weeks now in the garage trying to have the final braking issue sorted but, it hasn’t been going as straightforward as expected.......

The ‘new’ secondhand pump motor arrived and was fitted by the garage and to be fair, there was an assumption on the parties of all involved that the replacement would be the solution to the illumination and lack of braking power when subjected to lots of stop/start driving around town.

However, I picked the car up, drive it to the end in the lane - a very short distance and then had to hold the car on the brake at the junction and there it was, same as before!!

Car went back to the garage and after a bit of digging around, it appeared that the replacement unit appeared to have a possible leak from the body?
So, another pump motor appeared and was fitted......

I jumped in and started it and the ABS and the brake warning light illuminated for approximately 10 seconds before turning off. It didn’t have any other issues until I got home and as I negotiated the lane to home, the warning lights briefly illuminated during a 3 (ish) point turn into the drive!

I little bit of me is questioning are we looking in the right place or, is this a false diagnosis?
I’ve had the opportunity to use her for a protracted drive again, from home to Exeter, circa 100 miles and she drove lovely as ever and although the issue does seem to have reduced somewhat, the same symptoms remain, under protracted, not heavy but the stop/start city traffic the lights illuminate and the brake efficiency reduces and continues to do so until a point where it feels like I’m braking without a servo, I’m physically having to force the pedal down to get her to stop - it’s like the system bleeds out. However, as soon as she’s been driven again for 30/40 seconds, all the lights go out and the brakes are normal again!

I’ve subsequently driven from Exeter to Malmesbury where once again, I’ve experienced exactly the same symptoms...
Any suggestions?

I gave the car another oil change at the weekend, it’s the first time I’ve done anything significant to the car myself as I got the garage to do it.

Slightly annoyed as after telling the garage that I wanted the car sorting properly, I find underneath what is quite obviously a long term oil leak.

I have no idea why the garage didn’t tell me about this?
It could have been done when they had the car. I’m rather annoyed!!!

Also, the AC compressor has been disconnected and is siezed :roll:

But, on a positive note, it does seem low on corrosion.

Bitter sweet?
Perhaps the two things are linked? Oil leak and lack of corrosion?
As with any leak, clean it up, use brake cleaner and rags. Then you can better work out where it’s coming from, and how much of leak it is. A tiny leak over many years can look horrendous.

Compressor- you may want to consider getting it full refinished. Bearings and Seals. Then you have a warranty on it before getting it gassed up.

Or I have used spares here if you want another unit.
