As title says the head unit in my 'V' reg 99 D9 has a constant beeping when switched on.
When I first got this car 7 years ago there was a fault with both engine ECU and BSI. When cold, if you went downhill on overrun, the engine would run rough and the MIL would illuminate. If you stopped and switched the engine off, left it a few seconds and then restarted, the engine would run fine. The MIL would remain illuminated for a few days then go out by itself.
The problem with the BSI was that the Climate Control would not allow the A/C pump to cut in. I ended up replacing ECU, BSI and Transponder from another vehicle. At the same time I fitted an aftermarket Head Unit. When i plugged in PP2k, I noticed that I could now enable Cruise Control which I did. Climate Control now worked as did the Cruise control once I added the additional switch and stalk.
I have now decided to sell the car but wanted to keep the aftermarket Head Unit, so have refitted the original unit a Clarion PU-1633a. Since refitting the head unit there is this annoying beeping. Will this have to be synced to the new BSI using PP2K?
Hope someone can help.
