The Porsche 924 has a very special place in the German manufacturer's history. Before being the luxury sports car brand that it was today, it struggled through the 70s just to keep afloat. It was the 924 that saved the day for Porsche-generating enough revenue to raise the company up and providing the funds to promote the development of the 911 which would go on to be one of Porsche's most iconic and recognizable brands. Today the 924 is considered a classic, and a dream of sorts to many collectors. The following are the most common problems encountered with the 924.
Because of the age of the Porsche 924, a lot of the body work did not benefit from zinc-plating-especially those released prior to 1980. This zinc plating is the reason why a lot of vehicles today remain in tip-top, un-rusted condition even under the worst circumstances. The rusting on the 924 is most visible in the car's lowest extremities. Particularly vulnerable areas include the roof gutters, lower door sections, and the front wing edges. Apart from the aesthetic, rusting can cause a dangerous breakdown in the body.
While the solution may be obvious, it is not advisable for anyone to undertake anti-rusting themselves. Unless the one doing so is a trained or experienced restorer, doing so might do more harm than good. Zinc-coating after such restoration is advisable.
Another problem commonly manifested by the Porsche 924 is that it will occasionally be difficult to start. Many immediately assume that it has to do with oil leaks or faults with the engine block itself. This is a dangerous assumption that has led many to splurge on engine re-tunes or replacements only to find that the problem persists. The many fault lies within the fuse and relay box. Over time, the contacts inside the box fuse completely open or closed due to repeated heat-ups. While the problem is extremely inconvenient, it is not as dangerous or life-threatening as one might think.
An upgrade to Porsche's more modern DME relay permanently fixes the problem-the trick is to get it brand new.
