Mgzs horn not working checked fuses


Own an MG Rover built after August 2003? Is one of the following not working:
Horn? Drivers electric window? Central Locking? Fog lights? Intermittent wipers?
It is very likely going to be one or several of the Pektron relays in the SCU unit that have gone. The relays are readily available for about £5 each on the web. It can all be fixed in under a day with some soldering tools, sockets, patience and perseverance.
Such a shame one small component, not even made by Rover, have just a detrimental effect on electrical reliability.
Here we fix a 2004 MG ZR but the Pektron relay are also used in the MG ZS, Rover 25 45 and MGF, so the general instructions are also applicable to them. Just the location of the SCU unit will vary.
On the MG ZR with a/c most garages will say the a/c has to be degassed etc (more cost) but here we leave the a/c connected. The SCU unit can just about be wiggled out from behind the a/c evaporator(radiator) unit with it still connected if some of the pipes clamps are loosened.

I had to replace the winshield wiper motor on my 1999 vw passat and in order to do so i had to move the black box seen in the picture out the way and had to unplug 4 plug-ins which colors were black purple...


You have lost power to the main computer, the dealer must reprogram it now to repair the no start. Sorry, never disconnect the battery or computer or this happens on any VW with VAG control systems

I recently purchased an Audi A4 2003 and when I went to get the car smogoglll


John it has been my experience that if you keep clearing the computer eventually the component that is bad will finally go bad and the car will not crank. I would first try the cam sensor due to the inexpensive cost of the part. I had a k1500 pickup that you could reset the computer and the truck would run fine for a month and then it would act up again I replace the computer and the problem was solved. The dealership may not want to replace the computer due to the expense and due to the mileage on the vehicle. If they buy the car back they will reset the computer and sell the car with no warrenty and out the door it goes with no recourse by the buy. I am not implying that they will do this but it is an option.

My cd player wont work..It keeps saying error 20..I was wondering what I could do to fix it


I believe error 20 is a laser focus error, if all discs don't work unit will need repair or replacing (most likely replace due to repair cost)

Leaking Coolant - Water Pump Replacement


Depends on your experience, confidence, what tools you have and how much risk you can tolerate if you get into the job and can't finish it or do it incorrectly. A water pump poorly done could result in a damaged engine. It's a fair ways complicated for a novice but within the range of someone who's done brakes or replaced belts, hoses alternators etc. To see what you have to do, find a repair book for your car at the library. Otherwise it will cost somewhere around $200 to $400 depending how complicated the repair.

Immobilizer


If there is a blinking car icon with an "X" over it. This icon means the Immobilizer has been activated and hence won't allow the car to start. It could be due to a bad SCU, Start Control Unit. The SCU is actually the ignition switch on these cars.
Most of the time it's triggered by the anti-theft system..You can try this trick i learned that the dealers won't tell you...try locking and unlocking of the doors five times with the remote to reset the immobilizer and see if this helps.
Good luck..i hope this helps...please take a minute to rate me a fixya.
