Have the exact same problem. Drivers side blinks on then off. Passenger side works fine. I removed the passenger side seat heater and plugged it into the drivers side and still the switch will blink on then off. Any suggestions on what to check next? And yes, trying to route the passenger side harness out was a pain in the .

Sorry don't mean to bump the thread, but I just noticed that my coolant color is yellow. I was going to get more coolant and the Porsche Parts Guy said the color should be Pink and that you should not mix coolant types. Should I stick with Yellow coolant? Thanks!!

Quick update. Found the leak. Coolant Expansion Tank problem +0. Idiot +1. It ended up being the hose leading to the engine. The clamp wasn't tight enough. I just tightened up the clamp and viola leak is gone. This is my second clamp issue. Well, to quote Snoop Dogg "You got to check them hose..." Thanks for all the help!!

I considered that but I tend to change out vehicles pretty often and it looks like the Durametric is limited to only Porsches and limited to 3 vehicles. Yes, I probably won't have more than 3 Porsches in the next 10 years but if I'm shopping for one in the future I would like to be able to plug it into multiple vehicles to figure out history information. Are there any other options out there?

Thanks again Maurice Yeah I need to revise all that previous speculation. When I got home I checked the pressure release valve and it was not popped up. I'm assuming that means there was not excessive pressure. I also didn't see any residue indicating an excessive overflow that would account for the dump of coolant. I was also wrong about the coolant level. I checked again and it was close to min. So looks like a pressure test is in my near future. Probably will end up being the coolant tank. Will update. Any coolant suggestions? I've read some back and forth about using only Porsche or VW coolant over regular Prestone. What I did find, in the picture below, is what was probably causing the P0491 and P0492 CEL. I'm no gear head but I'm pretty sure that hose should be connected to the secondary air blower. Hose clamp must had fallen off. Is there a way to clear the CEL without disconnecting the battery? Otherwise I'll be posting on the Radio Code Help sticky pretty soon...lol.

[ here are two possibly too simple questions that occurred to me: when the problems started was the coolant tank too full? and, has the coolant been cut with water? whats the coolant/water ratio? If there's water in there, could the water be overheating and causing the leak? Just a thought.... stay with it.... good luck. Hummmm.... the coolant tank could have been over filled. If you look at the first set of pictures you can see the large puddle of coolant on the ground yet my tank was still pretty full. There was also a huge cloud of steam coming from the engine on the way home so no telling how much spilled out at that stop light. It's kind of hard to tell the exact coolant level looking through the plastic, but it is near Max. If the majority of the overfilled coolant did expell itself that could be why I'm only seeing a small drip at this time. I'm tempted to take her out again with a little more "spirited" driving to test your theory out. Where does the coolant over flow normally go? I just purchased the car so I'm not sure what kind of coolant or at what ratio it was cut. The engine temp hasn't gone over 182ish since I started monitoring it, but I haven't been pushing it either. Thanks judgejon appreciate the reply. Though I want to join the +1 Cracked Tank Club on the forum I also don't want to. ;)

Thanks Guys for all the advise. As much as I would like to try and diagnose the problem myself I think I'm getting to the point where I'm just going to take it into a pro for a diagnostic. If it's a simple fix I'll try it myself. Anybody know a good Indy in the Plano or Dallas Texas area?

kcs: Since your coolant cap ends in "01", definitely start by replacing the coolant cap. Since you have gotten a CEL, go to any auto chain store and have the code(s) read and post them here. If the CEL starts flashing, don't drive it as at a minimum, you may damage your catalytic converters. The "steam" that you see may just be coolant leaking onto the exhaust, but you have to pinpoint the cause of the leak. Eliminate the coolant cap from the equation and go from there. Regards, Maurice. Thanks for the advise Maurice. The CEL was not flashing so I went to down to Autozone to get the CEL checked out. It came back with code P0491 and P0492. Something about insufficient air flow, possible air solenoid valve or faulty relay. I'll have to research that on the forum. Do you think that has anything to do with the coolant leakage? I got the new .04 coolant cap and put it on today. I drove it around for about 10 miles at low RPMs and the temp stayed around the 182 range the whole time. When I parked the car there was still a slight coolant leakage from below. I attached a pic. No steam this time so it seems to have improved a little bit. Not sure if the new cap had anything to do with it or not. In the picture you can see the coolant. Not sure if it's coming from there or dripping on to there. I also checked the coolant and there doesn't appear to be any oil in there. I opened the cap to the oil and it looked a little suspect. It almost looked like curdled milky residue if you can see in there. When I checked the dip stick the oil looked ok.

UPDATE: So I figured since the coolant level was ok I was going to try and run the car for a bit and check out the engine temp so see if there were any issue. I drove around for about 15 minutes closely eyeing the temp gauge. I didn't pound on it any just nice casual driving below 5000 rmp. The temp stayed around 182 the whole time. Didn't see any issues at that time. I stopped in a parking lot to check for leaks and it seems like once you let the car idle then it starts to leak. This time it didn't dump all the coolant just a steady drip. If I rev up the engine, even slightly, the leak will stop. So I headed home and every time I stopped at a stop light I would see a little steam coming from the deck lid in my rearview. I would give it a little gas and the steam would go away. Oh yeah the check engine light came on this time. I tried to use a flashlight to look for the leak source but couldn't pin point it. From the engine compartment the tank looked fine. Nothing leaking around the cap. Couldn't see anything uptop leaking. I couldn't get a good look from underneath Any ideas? Should I not try driving it again? Don't want to do further damage. Should I start with replacing the cap then go from there? Thanks!

I had the same issue with the flickering lightsbefore. I use to have to keep flippingit from the on and off position about 5 times before the lights would comeon. Eventually they stopped coming on alltogether. I can't find the original post but it was basically takingthe light switch unit out and tapping on it with a hammer. I know sounds like something Fonzie would dobut it worked.

Try 1096 or 1094 Thanks!!! 1096 worked.

Another radio code needed :( CDR-220 Becker Type: 4462 Serial: 15088201 I'm tired of listening to my iPod in my car...lol Thanks!
