Ok, so I am new to the water cooled vw's. This will be a little long but I do not want to leave out anything. I bought this 2013 VW Beetle TDI Fender edition Dec. 22 2025. Here is what I knew when buying it, it has the egr and dpf deleted with a stack. Tunezilla Stage one tune for the delete. It was in limp mode, he said he parked it and the next day it was having issues (I call BULL) 139,665 miles, DSG Trans. It does fire up and run and move but stuck in limp mode, He replaced the engine wiring harness due to original getting damaged some how. it had a few codes with a normal scan tool. Code P13d6, P13d0, P00AF, P0118 and P0641. I replaced all 4 glow plugs to eliminate P13d6 and P13d0. I replaced the actuator to get rid of P00AF, and one of the coolant temp sensors wasn't connected causing P0118. I checked the MAF sensor and cleaned it. Now the only code on my basic scan tool is P0641. still fires up and runs but still in limp mode.

Here is where things start to get weird. The windows worked when I got it, but then they stopped, found the switches on both doors had corrosion in them so I replaced them, Windows switches work, but driver side master will not roll down the passenger window. Plus after a few minutes the windows stop working, I have to unplug then battery then plug it back in and they'll work for a few minutes then stop, plus they don't do the little roll down and back up when opening and closing the doors, I've tried the push the buttons down and hold for 5-15 seconds and on the up, doesn't fix the issue. That's one issue that wasn't there when I first got it. Weird thing is the remote mirrors were not working and now they are working. Door lock sensors on the handles are functioning even tho VCDS is showing something up with them. Sunroof is functioning with no problems. High beams are not turning on. All fuses are good, not sure about relays since I cant seem to find an info on which does what really.

Next the steering wheel controls for the stereo and dash controls worked when I got it, but now they don't and the horn no longer works. Didn't do anything that would affect the clock spring, I pulled the clock spring out, checked all connections, and checked its internal ribbon and connections, All are good. But just don't work or light up. I checked the wiring at the steering wheel and its connections all the way to the main harness into the BCM, no brakes in the wires. Stereo and nav are working even tho vcds shows codes for it, but I am assuming that is do to the steering controls failing.

Back to the motor. I checked all grounds, Good connections and checked with multi meter. Checked alternator output, it was 14.6v at the battery. Motor harness is new. I have checked all fuses, all are good, not sure about relays, partly due to I cant find anything telling me what relay does what, and it doesn't have the infamous 109 relay. I just checked the MAP sensor and tested its voltage at the wires and with the motor off but power on it is getting 5.8v, I know this is to high, should be between 4 and 5v. I am beginning to think the ecu and bcm are having issues.

One of the HVAC Lines is disconnected and system is currently empty so that is why it shows up in the scan.

My first time scanning it with VCDS it gave me a 02- Auto Trans -- Status OK 0000, But now it is giving me a malfuntion with it.

With all the weird working then not working and high voltage at the MAP I am thinking there is a problem with the ECU and possibly the BCM. Here is my scan.

I would start here:
001601 - Sensor Reference Voltage A
P0641 - 000 - Open Circuit - MIL ON
The ECU has a 5V "reference voltage" output for various sensors. It monitors the current being drawn from that output, and this DTC sets when there is none. Possible broken wire?

I would also clear all fault codes and then see what comes back. Many of your fault codes are flagged "Intermittent", meaning the fault condition that fault condition that set the code was no longer present, or could not be detected, at the time the scan was performed.

As Uwe mentioned above, regarding your scan and fault code, here is some information I thought could guide you in your checks / search. I sure matches your description in your initial post!

It has a new engine wiring harness, so theoretically there should be no breaks. But I am going to check more tonight if I can figure out what pin at the ecu end of the harness is the map. I still need to check the tps and iat sensors I have tried clearing the dtc's with vcds multiple times, and keep getting the same coming back. Also flashed back to stock tune and reflashed the dpf/egr delete tune back in. Didn't help, dtc's just keep coming back. There are multiple plugs around the motor that are not plugged in to anything nor is there anywhere to plug them in, most likely plugs to the no longer existent egr and dpf. I'm still searching, and looking for any ideas i haven't tried. I'll keep you updated.

Thank you. It gave me a couple other things to look at, just need to figure out what pin does what. But looking more and more like a failing our damaged ecu.

Define "New" please and where did it come from ??
Lol. Valid point. The previous owner stated it was a new harness. The motor bay and motor was very dirty but the harness was extremely clean and it had oem tags/ sticker, or what looked to me as oem tags on the harness. Either way it is easy to tell that the harness is newer then the motor. But where it came from i have no clue. I will be doing more tracing. But the previous owner replaced it because a part under pressure had a blow out of some kind taking out a section of the engine harness. That's why it got replaced, also why I am thinking there is something wrong with the ecu. The engine was obviously running to cause this blow out that ripped thru the harness, this would cause multiple wiring direct shorts going back into the ecu. Just my theory.

Well it would do - You can only buy a harness from a dealer and I would imagine it will have to VIN Specific - Am I right ? Anyone ?

Just my theory.
For now untested - so not applicable in a diagnostic process !!

001601 - Sensor Reference Voltage A P0641 - 000 - Open Circuit - MIL ON
You have to solve that first

That guidance from @Uwe is bang on - Why have you asked for advice and not taken it ??

You need a new new harness !!

I bought this 2013 VW Beetle TDI Fender edition Dec. 22 2025. Here is what I knew when buying it, it has the egr and dpf deleted with a stack. Tunezilla Stage one tune for the delete. It was in limp mode, he said he parked it and the next day it was having issues (I call BULL) 139,665 miles, DSG Trans. It does fire up and run and move but stuck in limp mode,

I hope you paid scrap value for it - Will you ever do anything with it other than scrap it ???

Its a 2013 Beetle - These things have little value. They were not a great car when they rolled off the production line. If you ever get it going you will never recover the cost of your time never mind the cash !!

There isn't much that's "under pressure" in that engine, unless you're taking about engine internals, and I'm sure you would've noticed if internals came out of the engine.... so you have some a few short high pressure fuel lines left.... your theory is kinda silly.
with a stack.
Face it... you bought an already butchered vehicle.... I'm sure there will be a lot of sorting out to do. Anything the previous owner did, he more than likely f@cked up

Before he does any sorting out, I reckon he will spend near a lifetime undoing the previous "butchery" Only then can he have a fresh canvas to build on !!

He bought a cheap car !

I could not afford to buy a cheap car ? Not on my six figure salary (after tax)

I am taking in all this advice, at work currently. So when I get back to my shop I will be putting all this advice to work. Electronics are not my strong point. Most of my cars are from the 60's lol. All be it i have a few newer, but never had to really chase electrical problems in them. And it's hard to find out I'm phrasing it wrong in my searches. Can't even find a diagram for the relays under the dash and what the exactly control, just a diagram for the fuses. Either way when I get to my shop I am gonna do my checking on these things I'm advice to, although uwe's link did state a faulty/ malfuntion ecu. But I will try to see if I can find this open circuit. Just be nice if somewhere it stated all sensors that are on the same circuit as the map? Looks like maf, iat, tps? Am I missing any to check. I have not checked the iat or tps yet.

Turbo system is under pressure. Either way just going off what he said. Yes there is some stuff needed up, wife liked the stack, I did not, got it for her. Not my first time buying a car with problems and fixing it, just this one is more computer issues then I've dealt with in the past

Ok, I came here for advice/ ideas and help, not to be chastised and ridiculed for my purchase choices. I've bought many cars over the last 34 years and done lots of builds. I once bought a mini cooper s with a trashed cylinder, I replaced the motor and it was a good car my wife liked and used til she got tired of it. I bought an 01 jeep wrangler with a seized motor, I put a new motor in and was a great jeep. Don't mind getting my hands dirty, done lots a car flips, buying mechanic specials, fixing and selling them for way more then invested. This beetle the wife wanted to use to drive to work and stop putting so many miles on her favorite ride. Either way the price was good, motor fired up and ran and moved, just limp mode. I knew I'd be chasing some demons. So unless you have actual useful information or advice, I don't need to hear about your 6 figure salary and what you can and can't afford, nor do I need you to make comments ridiculing me for a vehicle I bought.
Thank you for any advice you may have provided.

Ok, so I am new to the water cooled vw's. This will be a little long but I do not want to leave out anything. I bought this 2013 VW Beetle TDI
Since when was a 2013 diesel beetle water cooled ???
