Hi, new to the forum. Got a question. 2008 Beetle convertible, 2.5 engine. I've had a TPMS light on constantly for a while with no low tires. Matter of fact i just put new tires on it. Now my EPC and traction control lights are on. Car runs fine though. I see a lot of posts on here about checking the throttle body, MAF, etc. Sounds like it could be a number of things so it needs to be scanned i would think. Has anyone ever bought one of those vag-com cables off ebay? I am pretty technically inclined so could hook it up and read it i suppose but there is such a variance in price for those things, are the only ones worth a @#$% the $200+ ones? I'd like to avoid taking it to the VW dealer if at all possible. Thx for any input you have.
