Wedged the GTI's radiator in. I was pretty worried about the Nissen OE equivalent I bought on FCP euro being enough for the VR6.

Pros: Nissens is good brand

2004 E46 320i manual with 116k miles. Bought it just over a year ago for \u00a32000 probably spent around \u00a31000 on it (radiator, air con, rocker cover gasket, oil sensor, boot switch, coil pack), not too bad for a 20 year old car I don\u2019t think. Only thing that doesn\u2019t work on it is the cruise control, it used to but recently stopped.

Pros: not too bad

Cons: cruise control stopped

Vehicle: BMW

Mileage: 116000 km

It happened to me once at a night time. I just pulled over, stopped the engine and started again after several minutes and everything was OK.

Edit: After reading other's comments, I realized that mine also related to coolant system. Some time after this incident I replaced radiator because of a coolant leak. May be this warning is related to that.

Pros: Everything was OK

Cons: coolant leak

The ~2014 Nissens, with the 15 round tube design just doesn't cut it. From what I can tell the car would've come with the 30 flat tube design. The Nissens just doesn't have enough surface area. On a hot day, with the AC going and highway speeds it just couldn't keep up.

Cons: insufficient cooling, low surface area

Vehicle: Audi
