95B Autel Scan Codes - Can someone point me in the right direction?
Hi all,
Been on a lurker on macanforums for awhile and finally got my first Porsche, '18 Macan 2.0.
Ran into my first set of DTCs with my Autel and need some help (macanforums had no answer, and the search here I didn't find much).
CODES:
000602 - Closed-circuit current, limited exceeded (eEm)
000603 - Load switch-off (eEm)
008142 - Water pump relay, short circuit to B+/open circuit.
I did find someone with a CD that had the 000602 and 000603, but it looks like it was battery life related. Zero luck with the 008142.
No CEL. Car has ~17k mi. Service at 10k @ Porsche was 100% normal.
I would take note of the code(s) and clear them with your Autel. Chances are they're likely transient issues.
It's essential to remember that these cars are electrical hogs, so a well charged battery is a must. Failure to keep it on a battery tender when not in daily use will start generating numerous error codes that will have you chase irrelevant issues.
So check you battery both are rest and under load, if satisfactory, clear the codes and see if it recurs.
I remember reading in the manual that it needs to be daily driven or tendered. Suppose it's more necessary than I thought. FWIW, my drives are averaging 1x a week for about 50 mi. in 1 instance. So, you may be right.
Quick experiment, LMK if this would work: Clear codes, drive around, rescan.
a) If errors are no longer present -> tender will fix
b) If errors are present -> different issue.
FYI, certain codes take several cycles to clear.
But...
Are you getting any unusual rise in coolant temp? Any leaks? What's the status of your battery (at rest, under load and age)?
Check if the coolant pump control relay is corroded or any sign of leak near there. Sorry the best I can suggest. HTH

I sure hope there's no issues. I do my own routine inspection every wash and 5k, and everything is static - so good. As far as the battery, I noticed the it ranges from 12.6V when off and 13.2-13.7V when running. Pretty typical. Battery is original, car's a '18.
I'll take another look re: the relay.
Also, just got myself the charge-o-mat pro. Planning to run that for awhile, reset, etc. and see if the code returns. Fingers crossed, it's gone.
As I mentioned, certain error codes takes several cycles (start/stop - meaning engine off) or miles to clear. I don't know if it specifically this applies to this error. The fact that the other DTCs disappeared is a good sign meaning they were transient. Keep a note of them in case they reappear.
The battery looks good and anytime you won't be driving it for several days, put it on a maintainer. Let us know about the relay.
I assume we are talking about a 2018 Macan 2.0 4 cylinder engine:
The code sounds like it is related to the Relay or fuse for the After-run/Auxiliary electric coolant pump.
The pump itself might be the root cause of the relay or fuse failure, this pump has a long history of coolant leaking into the electric motor/control side of the plastic housing, and shorting it out....sometimes causing fires....there was a safety recall on this some years ago.
The pump is usually located below the intake manifold, on the driver side of the engine.
