Quite a collection of coins there!

I thought when people referred to classic cars as money pits they meant something else. I'd keep digging, "there's gold in them thar hills"

Testing...

 

 

Actual Faults

 

 

Washed off a few months of dust.
No test drive because workmen are ripping up the path outside my house!

He he - brilliant...   are they real faults though?

 

I think she'd drive me nuts on a daily basis   😉

Patrizia now has her own speaker, mounted at the back under the driver side dash.
She's constantly chatting about checking oil level, and wants me to check my brake pads.

Also my Blaupunkt SQR46DAB arrived from the UK.

 

Got it powered but had to wait another week for new double-shielded RCA cables as they were amplifying engine revs through the speakers!

I decided to study some wiring diagrams to troubleshoot the constant "Check oil level" warning. The cat had other ideas..

Under tray re fitted.
This is an aftermarket piece from Classic Quattros

Based on some initial research, wiring diagrams and a Classic-Audi forum post from Darron Edwards from 2012 🙂
There's a .25 BAR oil pressure switch with a single wire which it uses to trigger the warning, that connects to delay relay 234 under the dash. That in turn links to Patrizia for the voice warning and to the digital dash to turn on the oil pressure warning light.
Next step is to check that relay, wire continuity from the sensor, and to the dash and patrizia.

Hmm, relay unplugged, no oil light on dash but Patrizia gives the warning. Relay plugged in I get both. Definitely have connectivity from oil pressure switch to relay.
 

Finally the RCA cables arrived so I could fit the stereo properly and reassemble the interior.

Out of the driveway!
Drives okay, ABS issue I had is gone but there's a new one.
Sounds like the pump running for a bit, then stopping, then running. But brakes work well.

I take it the Blaupunkt is a modern unit with a retro look?

 

I've just got a replacement headunit for my 1995 MX5 but managed to find a working original Clarion CRX87RM from a Fiat for £7 but just need to change over the front panel as it's Fiat Branded - no DAB, Media or Bluetooth but at least it works with the CD multichanger...   ;-)

I hope that CD player has autoreverse, as all the best system had in that era

Hi Rob,

 

Is the brake system holding pressure with the the engine running?.

 

I would be inclined to jack up each corner in turn, drop it onto an axle stand, start the car and then get someone to bury the brake pedal while you check for any seepage.

 

The abs system runs at a fairly consistent pressure, and as such, will put more load on the line connectors than just trying the system with the engine off.

 

Also, being an older design, and more of a pioneering ABS system, there is more potential for small air locks than a more modern system due to pipe run designs not being as well thought out as they are today.

 

All that being said, I would still have one in a heartbeat.   

 

 

Yes the head unit is a new model styled after the original 80s Bremen unit.

It has Bluetooth, radio, pre-out for amps, aux, usb, SD slot and DAB

And 4096 lighting colour choices.

DAB isn't a thing here but the rest is just what I needed.

Failed the WoF - ABS light came on during the test drive.
Brake light was fixed with contact cleaner. Haven't checked headlight yet.
And it seems the odometer lighting bulbs have gone off again. Easy fix

One day Rob...one day  

Took the cover off the abs unit to check out the relays. Those wires don't look too clever.

Taped them up for now. Checked the ABS relay too and it's all correct as far as expected input and output voltages.

So I'm kinda over it now. I've dropped the car at Auto Brake and Clutch who fixed a mate's Coupe quattro ABS a while back.

Always good when the business owner says "You know it won't be cheap, right?"

Longest drive in 2 years, about 20km. No drama and the car felt good at 100kph

Noooo you are too close to the that Suzuki, it may 'dink' your door....MOVE IT NOW...IMMEDIATELY...I WONT SLEEP UNTIL I KNOW IT'S SAFE!!!!!

Ooh thats a bit touch and go. Somewhere near the maximum arc of the Suzy and the Toyota door swings. I'd get them to move their cars. Seems only reasonable 

 

Hope this helps

The parks were at about 35 degree angles too, glad my handbrake works.

Yikes, Somethings got a little close in there, the yellow trace wire looks to have issues too.

 

When he said it won't be cheap, did he suck air through his teeth at the same time?, that's usually a sign of impending pain.

 

I think you've probably found your issue there, looks like the previous owner fancied himself as a budding auto sparky, but his ambitions exceeded his talent.

 

Good luck with it all Rob, keep us posted.

You just described me

ABS vs. non-ABS.
Waiting for a quote to make my car look like the first one.
Weight saving bro!
Then I have to get it certified without ABS.
Then I can get a WoF.

I'm still torn between fixing or removing.
Removing means it can't break again, or continue to be unreliable. 
Lots of old cars don't have abs.
But it is a factory feature. 
But then so was the original carpet, upholstery, paint, heated seats, stereo, and they're gone.

Alright, I'm coming around to the idea of troubleshooting it more myself. I was putting an arbitrary time constraint on things because I wanted to get it to an event but there's no point rushing things.
Have ordered new relays, fingers crossed they are right
As for the controller - might be worth pulling it apart with Neill my favourite electronics expert.
