I've been doing some reading and apart from a potentially busted tail lamp or failed brake light switch, the other problem could be a throttle position sensor (aka accelerator pedal sensor) failure, or perhaps an O2 sensor failure. Constant flashing coolant light can be a bad gauge, a bad wire, a bad sensor, and a bad control unit. If still flashing and engine cold then either wiring (unusual, not unknown) or temp sensor faulty (black sensor I believe) again you should be able to disconnect and should stop.

Hi, there's no real way forward unfortunately without a diagnostic read out as it could be numerous things. Then on 8/28/09, VWoA issued another new DSG Service Program to address an additional 53,300 VW and Audi cars spanning the 2007 through 2009 model years.After dropping my son off he checked the rear lights, all was well except that one brake light didn't illuminate when the brake was applied. This is my second winter on the tune and have had no issues other than this GPL flashing which I noticed today. just back from a short journey, on leaving the glow plug warning light started flashing on the dash.

Unfortunately, some of the controllers of this vintage I have tested will give a false alarm with a perfectly good set of plugs. I thought I had problems a while ago with my mechatronics unit but turned out to be just a lose connection on my MAF sensor to my induction kit but all sorted now. After that everything has been fine with no glitches or anything, except it ran like shit for 20 minutes after that happened. I glance at the display panel and the flashing blocked PRNDS is there and the car had dropped into neutral I hit the brake as the green brake symbol is showing and it goes back into gear and drives fine all the way for the next couple of miles to work. everything still works perfectly and you can put it back in drive and nothing is wrong other than flashing.Once you get the car going, do the same test with the car running to make sure your alternator is putting out enough voltage to charge.

Since you really can't short the sender out to test it, there is IIRC about 180 ohms of resistance in the tips when they are in coolant. The UWB technology is a major advance and should prevent high tech thieves from replicating the key's signals and stealing the car. There is a little microswitch inside the gear selector unit that tells it when its in park - this commonly fails by intermittently sticking and results in the symptoms you are having.Depending on which controller is fitted to your vehicle, a flashing glow plug lamp indicates an open circuit plug.

Not sure if that can be due to winter fuel, the extreme cold, or whatever's causing the GPL to flash. Having encountered the flashing glow plug indicator followed by a limp mode a few weeks ago, I can give a few pointers. FYI, I have experienced a similar situation in the past, except then the middle light was flashing yellow.Happened at an inopportune time/place with no prior warning (no lazy starts/cranking over prior to this). I've just driven 4:45mins from Yorkshire to London and the car ran fine with no trouble at all, bar the flashing light, which kept flashing. The brake light switch is like two in one, part does the lights and part does the ecu so it could be that. This can get into the engine and cause damage but normally it doesn’t although the subsequent extremely important thorough clean out of the system takes a lot of labour time and the turbo is much more expensive to repair.
