GLC AMG Headlight Query

The dip on the right hand shouldn’t be lower, and your’s definitely is.
Nothing to do with oncoming traffic.

Thanks. That’s conflicts what others have said and on this thread too.

I’ve never owned a GLC before so I don’t know what’s right. The courtesy car I have doesn’t do it but the lights on that are really fancy.

Now I’m confused

It's not difficult, when you look at the data plate on the o/s B pillar, there is a little headlamp symbol along with a percentage figure.
this is the fall of the headlamp beam setting.
It only shows one setting, and not a different one for each side.
Different vehicles with an higher or lower mounted headlamp will have a different percentage of drop.
1% would mean that the low beam is at an angle of 1 cm at a range of 10 m

Thank you.

Unfortunately I don’t have the car to hand so I can’t check this setting. I doubt they will be able to spray and fit the handle tomorrow so it will probably be early next week before it’s back but the garage is over an hour away so I don’t really want it going back again.

Is this an easy fix or is there something up with the headlight?

You can adjust it with an allen key on the headlamp, the further away from the wall would ensure greater accuracy to get them both the same.
Just decide which one you prefer, the higher or the lower one.

I would say your light patten is normal?

Thanks again.

If it’s a simple adjustment I’m not sure why Merc are just not doing it while they have the car? Also it’s just had an MOT, I thought light adjustments is a fail?

Is the Allen key in an obvious position? I don’t really want to have to start taking bits off to get to it but if it’s a simple thing I just want my car back and I’ll do it myself.

 

[Muckypaps]

His beam pattern is normal, but the horizontal lines are at different heights on each headlamp.

Personally I'd advise against mucking about with the headlamps adjustments, given that you're not even sure there's anything wrong with it as is. If you're still concerned, and you don't trust the dealer, just take the car to a local MOT testing centre and ask them to check it for you.

Yeah, I don’t fancy touching it. Tbf the dealership have not been flakey with my list of snags, I was expecting some kickback but they said they have addressed all issues, I really wasn’t expecting a new door handle but they contacted Merc in Germany and they advised a new handle.

I’ve read about the intelligent light system, I’m not even sure if my car has that? Something about a setting about driving in Europe.

 

[Muckypaps]

I adjusted mine when I first bought it, as it looked slightly less different than your's, I decided on the higher setting.
When I got it back after it's B service I noticed they had dropped them slightly, but at least they're both level.

I’m another one who thinks that beam pattern looks normal. Flat then a kick up to the left then flat. The photo doesn’t seem to show one of the lights misaligned compared to the other.
Easy to check - put a jacket/towel over one of the lamps to block the beam and you should see they are exactly the same.
Fwiw I thought one of the lamps on my Lexus was low but checking them out, each headlight has an identical pattern with one of the emitters on each headlamp (triple emitters) deliberately putting a beam further than the ‘main’ pool of light. Pretty good as the normal cutoff is very sharp from light to dark and this softens the transition without dazzling.

 

[Muckypaps]

It’s got two Kicks but one has gone through the garden gate so you can’t see it.

Spoke to Merc yesterday who assured me my beams are correct. He said they were tested again on the MOT machine. I guess I just have to go with it for now.

Door handle getting painted and fitted on Monday, apparently so hopefully I should have it back on Tuesday, I’m getting too used to this 2020 model, I really like the interior lights and touch screen but there there is a 13k difference in price that I can’t justify, the engine is the same and the drive is pretty similar.

So, got the car back this week, all sorted, or so it seems. I had noticed the eco stop/start wasn’t working, constantly staying on amber, read it could be battery, app says battery is OK so I’ll just leave it until January.

Then today the adblue warning light comes on, I’m thinking it’s just had a service but buy 10ltrs thinking it just needs topping up. I manage to get about 3.5ltrs in and its struggling to accept anything more, strange. Then it says the fluid level could not be read.

Called assistant out. Battery is gone, needs replacing, great, £250 he says and he can’t guarantee dealer will reimburse that. Then checks adblue and says this fault
y129 metering valve at fault. And now there is too much adblue in the tank.

What has been a really crap few weeks since purchase this really tops it off. I’ve already been without the car for 1 week, I’ve only owned it 2.5 weeks. I’m going away for Xmas on Wednesday and the whole point was having a new car to drive in.

I have to say I’m really disappointed with the car from a dealer. I’ll be calling the sales guy again first thing, totally deflated.

The adblue level measurement issue does not sound like related to y129 but more on the level sensor at the adblue tank. Both seem to have been parts prone to fail and rather expensive.

Does this car have the small stop/start battery? Fails more often than the main battery.

I’m only relying codes the Mercedes assist gave me on the email report. I don’t really care what the problem is, it needs sorting and fast or that car will be back for sale on their forecourt.

Assist guy said the battery was £250 to replace with him, no idea on the size. I was willing to let this go until the new year but it’s going to have to go back to get the adblue sorted anyway.

With what has been a difficult week with a poorly child I didn’t think a 29k motor was going to add to my worries. Thoroughly disappointed so far.

I was mainly motivating you to look after the dealer that they fix the car and you can be sure they did it instead of clearing codes and hoping the faults would appear later at your cost. Insist a detailed repair description and parts changed and challenge the description if you feel in doubt (e.g. the level sensor versus Y129).

The small battery would not cost that much even at the dealer, if it even exists in this car.

Thank you, sorry I didn’t mean to appear rude.

Just waiting for the dealer to open…
