I'm noticing a fairly significant drip of something watery on the road every time I park up - it's like the trail of breadcrumbs in Hansel & Gretel! On inspection, it looks like it's coming from somewhere at the back, near the backbox on the exhaust, but not actually from the exhaust itself, as far as I can tell. Any ideas? Is it anything to worry about?
I don't seem to be losing any vital fluids like screenwash or coolant, so I'm hoping it's just some sort of condensation from the hot exhaust. There's no puddles in the garage or out on the road when it's been parked overnight.
I do, but this has been happening when it's bone dry. Until today, I can't actually remember the last time it rained on the south coast. Actually, if it had, I wouldn't even be able to see the dripping!
I'll get them to look at it when it goes in for service. I was kind of hoping someone would just say "it's 'such and such'" so I wouldn't have to even worry about it!
I quite often see patches of water under the rear bumper by each exhaust.
It's either rain water, condensation, melted ice running down the roof drains or it's condensation from the exhausts. Get it checked out for sure but if it's not identifiable as; petrol, oil, washer, brake fluid it's not anything of concern and can only be moisture from the atmos ..
There only seems to be the two front drains (front passenger and driver footwells) noted in the maintenance guide.
Even with 4 zone climate control (I have that option too) there's just a rear distribution unit, which doesn't have any drains. If it did, the unit is in the middle of the car and is unlikely to drain at the rear
With the 4 zone system in the 7P there is a second aircon evaporator / heater system in the the rear left side above and behind the wheel well. This feeds temperature controlled air to the centre rear seat control unit via underfloor air ducting for distribution to the various vents. If the rear AC is turned off fully I would expect nothing to drain but if left running on automatic then it would condense water out the drain. The drain hose location is just behind the rear left wheel well through the floor and is detailed on page 116 of the Erwin 7P manual HVAC section.
Might be a T5 cost cutting thing? The AC system overview only shows refrigerant lines running to an evaporator at the front distribution unit. That feeds a rear distribution unit that appears to just be a mixer.
