I just purchased a Curt hitch for my 2012 Golf TDI and have been doing the research about getting something to monitor EGT. There are several options and was hoping to get some feedback on which would be best. With all the electronics on our CR TDI's, would it be ok to get one of the digital units that hooks to the OBDII port, or get a pod gauge that I then need to run a probe to the exhaust somewhere? It's not like I'm going to be towing an extremely heavy load; motorcycle, mulch, or any other home improvement items, but would be nice to have the peace of mind to not do any permanent damage to the engine. Also the budget is a bit limited so I don't want to get too crazy with the cost of this. I've searched on this site to try to find out some recommendations, but all I can find is mentioning of EGT and how it's a wise thing to monitor when towing. Please help!!
