There is a design fault with the Macan rear wash/wipe system. My Mac is just out of warranty and has always been garaged overnight. However, I recently went on holiday and had to leave the car in a Heathrow car park for 2 weeks in February, when there was a cold snap. On my return the rear washer failed to work. I contacted my local Porsche dealer who said it was know fault on the Macan. The pipe leading from the washer tank to rear screen washer nozzle splits when you use the wash wipe, when it is frozen. My car was 4 months out of warranty and I was was warned the cost of repair would be £1500 as the entire interior trim has to be removed to replace the pipe. i contacted Porsche UK and they said they were aware of the problem and they might be prepared to contribute to the cost. The car is now booked in for the work, but if this is the fault then I trust they will pick up the total cost as it is down to poor design. If they don't, then I shall do my best to highlight the problem to the motoring press as I believe such a design fault is unacceptable from a supposedly engineering led company. One other word of warning. My Porche dealer they had quite a few Macan's in with the problem, but all were e dealt with under warranty, my crime was to keep the car garaged so it wasn't exposed to freezing temperatures. I suggested to my Porsche garage that at least the repair would fix the problem as presumably Porsche had modified the design to stop it happening again. No, came the reply, it is exactly the same design. So Macan owners be warned you cant use your rear wash/wipe in freezing temperature, because if you do it will cost £1500 to repair!
